Foldable vehicle shading umbrella

ABSTRACT

A foldable vehicle shading umbrella provides shading for top portion of vehicle. It includes a central hub holding a group of tubular elements extended form the central hub to hold the folding arms respectively, and the group of the folding arms radially extended from the central hub, and an awning shelter supported by the folding arms for sheltering top portion of the vehicle includes windows. Each of the folding arms includes two cylindrical rods and one pair of hinges. The two cylindrical rods are coupled with each other by using the one pair of hinges.

FIELD OF THE INVENTION

The present invention relates to a quick and easy operational foldable vehicle shading umbrella in an umbrella shape that can be unfolded to shelter the top portion of vehicle, to prevent direct sunlight and heat from entering into the vehicle, and folded into a convenient carrying unit.

BACKGROUND OF THE INVENTION

Parking in an uncovered parking lot is annoying to many people since the vehicle is directly exposed to sunlight during warm weather. The common solutions have been used and provided in current market are tinted window, reflecting panel, and etc.

The tinted window and reflecting panel work in the similar way by blocking the sunlight directly, reduce the heat entering into the vehicle through window and entire top portion of the vehicle to keep lower temperature inside of the vehicle.

The common disadvantage of above mentioned methods is that they do not prevent the heat entering through the vehicle body by heat radiation. Drivers always experience the heat flow blow into their faces when open the door of the vehicle after it had been exposed to sunlight for a while.

SUMMARY OF THE PRESENT INVENTION One objective of the present invention is to provide a foldable vehicle shading umbrella that covers the entire roof of the vehicle body, to effectively prevent the heat radiation rise the temperature of interior of the vehicle.

The present invention is to provide a quick and easy operational foldable vehicle shading umbrella can be unfolded to umbrella shape awning to shelter against the direct sunlight for the vehicle, and folded into a compact unit for carriage and storage.

Another objective of the present invention is an awning shelter is supported and stretched out in tension by a group of outwardly unfolded folding arms extended from a central hub. A group of tubular elements attached to the central are corresponding to the number of folding arms, in order to provide connection between the central hub and the folding arms.

Another objective of the present invention is the extraordinary vertical supporting method. It is different from the traditional ordinary umbrella with vertical center supporting rod, but using the edge of the top portion of vehicle as a supporting point. The folding arms sit on the edge, therefore, it will create a space between the surface of vehicle and the inside surface of the sheltering awning, in order to use the air in the space as insulation to reduce the direct heat from sunlight.

DETAIL DESCRIPTION OF PREFERED EMBODIMENT

As shown in FIG. 1 of the drawings, a foldable vehicle shading umbrella according to the present invention is illustrated, wherein the unfolded position for covering on top body portion of a vehicle to shelter the vehicle against to sunlight to prevent the heat from entering into the vehicle.

As shown in FIG. 2, the sectional view shows the detail of the inside of the umbrella. Each folding arm is secured separately onto the awning of the umbrella. Each arm includes one set of hinge 22, and each arm secured into central hub 10 with shaft 221 as shown in FIG. 3 in order to perform folding procedure.

The main working parts of the foldable vehicle shading umbrella of the present invention are shown in FIG. 3. The UV protection awning 40 is placed between the central station 13 and the central hub bottom cover 14. There are six tubular folding arm holders 21 spread outwardly and radially from the central hub, with an angle of 60 degrees between each other. Each arm holder 21 has been inserted long arm rod 31, and it also has extrude parts with a horizontal thru hole on it is used to connect the arm holder onto the central station. A small shaft 211 goes through the hole of the arm holder and the hole on the extrude parts of the central station part, to secure the arm holder and also provide frictionless pivoting as arm holder supporting walls, in order to perform folding procedure. The central station 13 is wider than the top cover 12, but with the same size as bottom cover 14 is. The way of the design of the wider central station 13 is to provide a supporting platform to the arm holders 21 to prevent bending over, since during the working—unfolded stage, the tension from the stretching of the fabric and the gravity of the whole umbrella will pull the arms toward to each other.

As shown in FIG. 3, the top cover of central hub 12 and bottom cover of central hub 14 will go together and secured by a screw 11 screws down from the hole on top cover 122 into the extrude which located at the center of the bottom cover 141. The extrude 121 on the top cover is designed with two main functions, one is to make the whole center hub to be solid and strong, another function is to fulfill the space between each set of arm holder supporting walls on the central station in order to limit the spacing of the shaft 211′, therefore, the shaft 211′ now is secured inside the central hub and will not fall out.

The one end of the long arm rod 31 is inserted into the arm holder 21, and the other end is inserted into one end of the hinge 22. Another relative short arm rod 32 is inserted into the other end of the hinge 22. The placement of short arm at the very outside, is due to perform the folding procedure. The short arm means it is shorter than the long arm enough to void block its way to be folded. Both snap ring 222 and shaft 221 used to complete each hinge set, and provide rotating motion.

As shown in FIG. 4, a foldable vehicle shading umbrella is in folded position. Each arm folded toward to center by bending over the hinge set 22 and arm holders 21. 

1. A foldable vehicle shading umbrella comprising: a central hub holding a group of rotating arm holders; a group of folding arms, wherein said each folding arm radially extended from said central hub, has a hinge connects between two cylindrical rod, one rod connects to said central hub with a shaft which provides rotating function in order to perform folding procedure, and provide tension to sheltering cover; a sheltering cover supported by said folding arms and using UV protection surface material.
 2. A foldable vehicle shading umbrella as recited in claim 1, forms umbrella shape itself by using reverse of traditional structure of umbrella without using any traditionally vertical supporting pole or side supporting pole.
